Example Embodiment
Specific embodiment one
[0073] This embodiment is an embodiment of a self-collimating device with high dynamic accuracy and large working distance.
[0074] The self-collimating device with high dynamic accuracy and large working distance of this embodiment has a structure diagram such as figure 2 Shown. The self-collimating device includes a light source 1, a transmissive collimator lens 21, a reflector 3, and a feedback imaging system 6. The reflector 3 is provided with an angle adjustment and measuring device 4; the light beam emitted by the light source 1 passes through a transmissive collimator. After the straight mirror 21 is collimated into a parallel beam, it is reflected by the mirror 3 and incident on the surface of the measured object 5; the beam reflected from the surface of the measured object 5 is reflected by the mirror 3 and collected by the feedback imaging system 6. Imaging
[0075] The feedback imaging system 6 is arranged between the light source 1 and the tr...
